The inner and outer rings of tapered roller bearings have tapered raceways, and tapered rollers are arranged between raceways. If the tapered surface is extended, the tapered roller bearing will eventually converge at a point on the bearing axis, which is mainly used to bear the combined radial and axial loads. The axial bearing capacity of the bearing is determined by the contact angle A. the larger a is, the larger the axial bearing capacity is. The tapered roller bearing is a separation type bearing, and the inner ring with roller and cage forms an inner assembly, which can be installed separately from the outer ring.
Allowable angle error
Tapered roller bearings generally do not allow the shaft to tilt relative to the shell hole, if there is a tilt, the maximum shall not exceed 2 '.
Clearance
Single row tapered roller bearings have clearance only after installation and can be determined after adjustment by another bearing positioned in opposite direction. The clearance of double row and four row tapered roller bearings can be provided according to the user's requirements and corresponding standards.
